Individuals Tending Towards Savagery Is A Great Name For A Punk-Rock Band

Sentence of Dave has often discussed risk assessment . . . it's difficult to decide what to worry about in a world where so much unfiltered information is so readily accessible . . . and so I will place you on the horns of another anxiety-filled dilemma: should you worry more about Individuals Tending Towards Savagery, a radical Mexican anti-technology group that praises the writings of Ted Kaczynski and recently bombed two Mexican nano-technology professors at the Monterrey Technological Institute, or should you worry about their prediction: that nanotechnology research will result in the creation of nano-cyborgs, which will be able to self-replicate automatically without the help of humans and eventually form an exponentially increasing "gray-goo" that will smother all life on earth?

It isn't a great book but it involves this little robot creatures that occassionally attack people and I think they evolved from some sort of nanotechnology. It's Updike so there's plenty of goo, but not grey goo.
